Hello Dewstone, that's a hard one to answer since both of the routes are beautiful. I was on Kleine Scheidegg many times - from there the train to Jungfraujoch departs - and I really can't say which route I prefer, through Wengen or through Grindelwald. You could consider to take one route on your way there, and the other on your way back. The route through Wengen will give you some more spectactular views, right into the "Lauterbrunnental", you will see waterfalls. Taking the route through Grindelwald, you will have other wonderful views, for example at the Wetterhorn. So if you don't want to miss anything...
By the way, what a lovely idea, a surprise anniversary trip! I'm sure you will enjoy the Jungfraujoch, it's really very special.
